Pelvis Flashcards
pelvis
central role as biomechanical hub
- couples mechanical forces
- fascial/muscle connections
inominates
stabilize pelvic ring
pelvis
2 inominates and sacrum
anatomy of pelvis
ilium, ischium, pubis
fusion of these three bones
joints - SI, pubic symphisis, acetabulum
self-bracing mechanism
form closure
force closure
form closure
structural anatomy of wedge shaped sacrum
internal SI joint structures
keystone
compressive forces stabilizing arch
-just like sacrum of body
force closure
compressive tensile forces to create a form of stability
muscles and fascial tensions
innominate motion
rotation, flaring - physio
shearing - non-phys
rotation
physiologic
anterior/posterior
flaring
physiologic
lateral/medial
shearing
non-physiologic
superior/inferior
physiologic vs. non-physiologic
non physiologic is trauma - body forced out of its normal barriers
physiologic, wearing down of barriers over time
standing flexion test
gives laterality of somatic dysfunction
side of positive standing flexion test
same side as dysfunction
